EST covers key cities such as New York, Washington D.C., Toronto, and Miami, making it a critical time reference for millions of people.
How Eastern Standard Time Works
1. Standard Time (EST)
- EST is observed from early November to mid-March.
- During this period, the region is 5 hours behind Coordinated Universal Time (UTC-5).
- All major cities on the East Coast follow this time for official schedules, broadcasts, and transport operations.
2. Daylight Saving Time (EDT)
- Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November.
- Clocks are moved forward by one hour, effectively shifting the region to UTC-4.
- This change allows for longer daylight in the evenings during spring and summer months.
Pro Tip: Always verify whether the Eastern region is on EST or EDT before scheduling calls or flights.
